Very detailed and easy to understand guide. Thumbs up! But you have just given many scammers, potential scammers and other jerkoffs many reasons to be happy. If they didn't know how to do an RBF-enabled double spend, they now have all the necessary information. Even if it's a great post, it will surely be misused. Sad

Nah, it's only effective to those who accepts 0-confirmation, plus it's the example on what happened to OP.
It will never be an issue for usual bitcoiners, Exhanges and "well-built" services that accepts 0-confirmartion deposits.

I still haven't upgraded my Electrum from 3.3.8 so the steps are a bit different on the old version.

It's pretty much the same except the button for coin control will redirect you to the send tab and "copy to clipboard" looks different but in the same spot.
